Hi
This is possible if you use the "jsTRF-Path Control" and "jsTRF-Path Trigger" rules on the DLS by brummfondel. You will also require his "Pathcontrol setpath" and "Autodrive" driver commands to go with them.  Each signal along a path has to have a unique name and it does take a bit of time to set it all up but I have found it to be well worth the effort.
